Toy stores are fun, but you probably stopped using the word “cool” to describe them when you outgrew your last pair of light-up sneakers. Toy Tokyo, however, is very cool, with something to keep you, your kids, and anyone else who might tag along entertained for hours. At its heart, this East Village boutique is an alternative toy store dedicated to futuristic, offbeat finds from Japan, Hong Kong, and the U.S., such as wind-up robots, anime and manga action figures, and all manner of remote controlled gizmos and doodads. This much will make it a hit with your kids, who will squeal with delight when they see the walking Electron Robot that all but begs to go home with them. But you and any other grown-ups in your group will quickly notice the owner’s artistic sensibilities, which come to life in the TT Underground, a gallery and event space below the store that explores the intersection of pop art culture and designer toys. Drop by after your shopping adventure to peruse the paintings, sculptures, clothing, and films that explore this fascinating world. Toy Tokyo is even entertaining when it’s closed, as the colorful mural on the store’s metal roll-up gate features some favorite cartoon and toy legends, like Bart Simpson, Batman, and Hello Kitty.
